I think i found a bug in the Belleza V5 -BENTO- 2018 body. There is a new updated Dev Kit for this body and all appliers which were created with the previous Dev Kit will no longer work.
I tested it with all appliers for belleza that i found in my inventory and none of them works any longer, they are dead, they do nothing. I asked then the creator from Lo's Inspiration for help with a outfit,
she sent me a applier to make sure that the one in my inventory wasn't damaged and that applier was as dead as the one which i had already. She then head to the Belleza Shop, grabbed the update
